Displays who is logged in to machines on local network
The rusers command produces output similar to who, but for the list of hosts or all machines on the local network. For each host responding to the rusers query, the hostname with the names of the users currently logged on is printed on each line. The rusers command will wait for one minute to catch late responders.
